Description

  The present invention relates to an instantaneous heating device that heats inflowed water to a predetermined temperature within a relatively early time and supplies the heated water to a user, and more particularly, minimizes deformation of a heating channel that is heated while water flows. The present invention relates to an instantaneous heating device that can be converted into

  A hot water tank is a device that heats stored water to a predetermined temperature and then supplies it to a user. Therefore, in the hot water tank, the temperature of the stored water should always be maintained at a predetermined temperature. For example, when the temperature of water heated to a predetermined temperature is lower than the predetermined temperature, the hot water tank repeatedly maintains the temperature of the stored water at the predetermined temperature by repeating reheating above the predetermined temperature. To.

  Thus, in the hot water tank, the temperature of the stored water must always be maintained at a predetermined temperature, so that a relatively large amount of energy is required to heat the water, and the water in the hot water tank is long. Since it was stored for a period of time, there were problems with hygiene such that the inner surface of the hot water tank was corroded by water and a water scale adhered.

  In order to solve the problem of the hot water tank, an instantaneous heating device has been developed. The instantaneous heating device supplies water to a user after heating water to a predetermined temperature in a relatively short time.

  Accordingly, since only a necessary amount of water is heated to a predetermined temperature and supplied to the user, energy required for heating the water is relatively small, and water is not stored, so that hygiene is improved.

  Such instantaneous heating devices are typically configured to directly heat flowing water. Therefore, the instantaneous heating device includes a heating channel that is heated while water flows.

  The heating channel directly applies heat to the flowing water, and the length of the heating channel is made as long as possible so that the time for applying the heat becomes long. Therefore, the heating flow path is formed by combining a large number of members, rather than being formed by a single member. For example, the heating channel is formed by a fitting method in which one member is fitted into another member.

  On the other hand, the heating channel is formed to have a predetermined volume so as not to locally overheat while water flows.

  However, when a heating channel is formed by combining a large number of members as described above, the heating channel is deformed when the heating channel is formed or when the instantaneous heating device is used, and the predetermined volume is not obtained. Occurred relatively frequently.

  As a result, the water flowing in the heating channel is locally heated at the deformed portion of the heating channel as described above, and is discharged through a discharge member such as a cook or a faucet. Sometimes water splashing can occur.

  When water jumps in this way, an accident such as a user being burned by the water that has come in may occur.

  One embodiment of the instantaneous heating device according to the present invention may include a water inlet 200, a fluidizer 300, a heater 400, and a water outlet 500.

  As shown in FIG. 6, water can be flowed into the water inlet 200 from the outside. Therefore, a water inlet channel 210 can be formed in the water inlet 200.

  The inflow channel 210 can be L-shaped as shown in FIG. 3, for example. However, the shape of the water inlet channel 210 is not particularly limited, and may be any shape as long as water can flow in and flow.

  The water inlet 200 can include a water inlet nipple 220. A part of the incoming water nipple 220 can form the incoming water passage 210 described above. The water inlet nipple 220 can be connected to a water supply source (not shown) such as a storage tank or a water purification filter by an attachment member (not shown), for example.

  As a result, as shown in FIG. 6, the water of the water supply source can flow into the incoming water flow path 210 of the incoming water nipple 220 and flow through the incoming water flow path 210.

  A sealing member insertion groove 230 can be formed in the water inlet 200. For example, as shown in FIGS. 2 and 3, a sealing member O such as an O-ring can be inserted into the sealing member insertion groove 230. Thereby, it is possible to seal between the incoming water part 200 and the incoming water side cover member 610 included in a cover part 600 described later that covers the incoming water part 200.

  The water inlet 200 can include a temperature sensor (not shown). The temperature sensor may be provided in the water inlet 200 so as to measure the temperature of the water flowing through the water inlet channel 210 of the water inlet 200.

  For example, the temperature sensor can be provided in the water inlet nipple 220 of the water inlet 200. However, the position of the temperature sensor in the water inlet 200 is not particularly limited, and can be provided at any position in the water inlet 200.

  The temperature of the water flowing through the inlet channel 210 measured by the temperature sensor is, for example, the amount of heat generated by the heating unit 400 when the water flowing through the heating channel R is heated by the heating unit 400 described later. Can be used when adjusting.

  As shown in FIG. 6, the water that flows into the water inlet 200, that is, the water inlet passage 210 of the water inlet 200 flows into the fluidizer 300.

  For this purpose, the flow section 300 can include a flow path forming member 310. As shown in FIG. 3, the flow path forming member 310 can be disposed inside the heating unit 400. A flow path forming groove 312 may be formed on the outer periphery of the flow path forming member 310.

  Thereby, as shown in FIG. 3, the heating channel R can be formed between the heating unit 400 and the channel forming member 310. And the water which flowed in into the inflow channel 210 of the inflow part 200 can flow through the heating channel R, as shown in FIG.

  The flow path forming groove 312 of the flow path forming member 310 can be formed in a spiral shape, for example, as shown in FIG. In this case, the heating flow path R is also spiral.

  However, the shape of the flow path forming groove 312 is not particularly limited, and may be a zigzag shape as long as the heating flow path R is formed between the heating unit 400 and the flow path forming member 310. Or any other shape.

  As shown in FIGS. 2 and 3, a first connection hole 313 for connecting the water inlet channel 210 and the heating channel R is formed on one side, for example, the lower portion of the channel forming member 310. Can do. Then, as shown in FIG. 3, a part of the water inlet 200 is inserted into one side of the insertion part 311 formed inside the channel forming member 310, for example, the lower part, so that the water inlet channel 210 is inserted. Can be connected to the heating flow path R through the first connection hole 313.

  Therefore, as shown in FIG. 6, the water that has flowed into the water inlet channel 210 of the water inlet 200 can move to the heating channel R via the first connection hole 313 and flow through the heating channel R. .

  As shown in FIGS. 2 and 3, the other side, for example, the upper part of the flow path forming member 310 is connected to a later-described water discharge flow path 510 formed in the water discharge section 500 and a heating flow path R. Two connection holes 314 may be formed. A part of the water discharge part 500 is inserted into the other side, for example, the upper part of the insertion part 311 of the flow path forming member 310, so that the water discharge flow path 510 is heated by the heating flow path R via the second connection hole 314. Can be linked to.

  Accordingly, the water that has flowed through the heating flow path R moves to the water discharge flow path 510 of the water discharge section 500 through the second connection hole 314, flows through the water discharge flow path 510, and is then discharged to the outside. it can.

  As shown in FIG. 3, a fitting hole 311 a can be formed in the aforementioned insertion portion 311 of the flow path forming member 310. As shown in FIGS. 3 and 5, the fitting hole 311 a of the insertion portion 311 is formed in the pressurizing member 322 included in the flow portion 300 and included in the contact pressure portion 320 described later. The fitted fitting protrusion 322a can be fitted. Thereby, the pressure application member 322 can be stably fixed in the insertion portion 311 of the flow path forming member 310.

  The flow path forming member 310 can be formed of silicon. Silicon undergoes relatively little thermal deformation and does not have undesirable effects on water, such as the generation of harmful substances such as carcinogens when contacted with water.

  Further, since silicon is relatively high in elasticity, the heating flow path R is formed so that a portion other than the flow path forming groove 312 can be easily brought into close contact with the heating section 400 by the contact pressure unit 320 as will be described later. can do.

  Therefore, when the flow path forming member 310 is made of silicon and the heating flow path R is formed with the heating unit 400, the heating flow path R does not deform or close due to thermal deformation, and flows through the heating flow path R. The water that you do is not altered.

The heating flow path R can be easily formed by the contact pressure unit 320 such that the portion of the flow path forming member 310 other than the flow path forming groove 312 is easily in close contact with the heating unit 400.

  However, the material for forming the flow path forming member 310 is not limited to the above-described silicon, and is relatively low in thermal deformation, no deterioration of water when contacted with water, and relatively high elasticity. Any known material can be used.

  As shown in FIGS. 2 and 3, the flow unit 300 may further include a contact pressure unit 320. As shown in FIGS. 4 and 5, the contact pressure unit 320, the channel forming member 310 is heated by the heating unit 400 so that the heating channel R is formed between the heating unit 400 and the channel forming member 310. 400.

  Thereby, the heating flow path R is compared with the case where the flow path forming member 310 is fitted into the heating unit 400 by the fitting method and the heating flow path R is formed between the flow path forming member 310 and the heating unit 400. Can be minimized.

  Therefore, when the water flowing through the heating channel is locally overheated and discharged to the outside, it is possible to minimize the occurrence of water jump, and the water that has jumped when locally heated and discharged Can prevent accidents such as user burns.

  For this purpose, the contact pressure unit 320 can include a pressure member 321. The pressing member 321 can be inserted into the insertion portion 311 of the flow path forming member 310 as shown in FIGS. 3 and 4. The pressurizing member 321 can pressurize the flow path forming member 310 toward the heating unit 400.

  As a result, as shown in FIG. 5, the flow path forming member 310 is expanded by its own elasticity, and a portion other than the flow path forming groove 312 of the flow path forming member 310 can be in close contact with the heating unit 400. .

  A plurality of such pressure members 321 can be provided. For example, as shown in FIG. 2, the number of the pressure members 321 can be two. However, the number of pressure members 321 is not particularly limited, and any number of pressure members 321 may be provided.

  Further, when the pressurizing members 321 are combined with each other, a hollow cylindrical shape, an elliptical cylinder, or a polygonal cylinder corresponding to the shape of the insertion portion 311 of the flow path forming member 310 can be formed. For example, as shown in FIG. 2, the two pressure members 321 have a shape obtained by dividing a hollow cylinder into two equal parts in the vertical direction, so that when they are combined, a hollow cylinder can be formed.

  However, as described above, the number of the pressure members 321 may be three or more, and may be combined with each other to form an elliptical cylinder or a polygonal cylinder.

  As shown in FIGS. 4 and 5, the pressurizing member 321 having the above-described configuration is configured so that all the pressurizing members 321 are inserted into the insertion portions 311 of the flow path forming member 310. It is possible to pressurize radially, ie radially outward. As a result, as described above, the portion other than the flow path forming groove 312 of the flow path forming member 310 can be elastically expanded and brought into close contact with the heating unit 400.

  The contact pressure unit 320 may further include a pressure application member 322. The pressure application member 322 can apply pressure to the pressure member 321.

  For this purpose, as shown in FIG. 2, the pressure application member 322 is a hollow cylinder, an elliptic cylinder, or a column corresponding to a cylindrical cylinder, an elliptic cylinder, or an elliptic cylinder formed by combining a plurality of pressure members 321. It can have a polygonal column shape.

  Further, the outer diameter D1 of the pressure application member 322 can be made larger than the inner diameter D2 of the hollow cylinder, the elliptic cylinder, or the polygonal cylinder formed by combining the pressure members 321.

  As a result, as shown in FIGS. 4 and 5, a pressurizing action is applied to a hollow cylinder, an elliptic cylinder, or a polygonal cylinder formed by a plurality of pressure members 321 inserted into the insertion portion 311 of the flow path forming member 310. When the member 322 is inserted, pressure is applied to the pressure member 321, and the pressure member 321 expands and simultaneously pressurizes the flow path forming member 310 radially outward.

  The heating unit 400 can heat the water flowing in the fluidizing unit 300. That is, as shown in FIG. 6, the heating unit 400 can heat the water flowing in the heating flow path R formed together with the flow path forming groove 312 of the flow path forming member 310.

  Thus, since the water which flows through the heating flow path R is directly heated by the heating unit 400, the water can be heated to a desired predetermined temperature within a relatively early time.

  The heating unit 400 may include a heating member 410 and a heater 420.

  A flow path forming member 310 can be disposed inside the heating member 410. As a result, a portion other than the flow path forming groove 312 of the flow path forming member 310 is in close contact with the inner surface of the flow path forming member 310, so that the heating flow path R can be formed.

  As shown in FIG. 2, the heating member 410 can have, for example, a hollow cylindrical shape. However, the shape of the heating member 410 is not particularly limited, and can be any shape as long as the flow path forming member 310 can be disposed inside, such as a hollow elliptical cylindrical shape or a polygonal cylindrical shape. .

  The heating member 410 can be formed of stainless steel. Thereby, since the heat conductivity of the heating member 410 is high and is heated relatively quickly by the heater 420 described later, the water flowing through the heating flow path R can be heated more quickly. Further, the heating member 410 is not corroded by water.

  However, the material forming the heating member 410 is not particularly limited, and any material can be used as long as it has a high thermal conductivity and has corrosion resistance to water.

  The heater 420 can be attached to the heating member 410 as shown in FIG. Further, the heater 420 can heat the heating member 410. Such a heater 420 may be a planar heating type heater. However, the heater 420 is not particularly limited, and may be any known one such as a heating wire as long as the heating member 410 can be heated.

  As shown in FIG. 6, the water heated by the heating unit 400, that is, warm water can be discharged to the outside through the water discharge unit 500.

  For this purpose, a water outlet channel 510 can be formed in the water outlet 500.

  For example, the outlet channel 510 may be L-shaped as shown in FIG. However, the shape of the water discharge channel 510 is not particularly limited, and can be any shape as long as the water heated by the heating unit 400 can be discharged to the outside.

  The water discharge unit 500 can include a water discharge nipple 520. A part of the water discharge channel 510 described above can be formed in the water discharge nipple 520. Further, the water discharge nipple 520 can be connected to a discharge member (not shown) such as a cock or a faucet by an attachment member (not shown), for example.

  Accordingly, as shown in FIG. 6, the water heated by the heating unit 400 while flowing through the heating channel R, that is, hot water moves to the outlet channel 510, and then the outlet channel of the outlet nipple 520. It can be discharged to the outside via 510.

  A sealing member insertion groove 530 can also be formed in the water discharge part 500. For example, a sealing member O such as an O-ring as shown in FIGS. 2 and 3 can be inserted into the sealing member insertion groove 530. Thereby, it is possible to seal between the water discharge part 500 and the water discharge side cover member 620 included in a cover part 600 described later that covers the water discharge part 500.

  The water outlet 500 can also include a temperature sensor (not shown). The temperature sensor can be provided in the water outlet 500 to measure the temperature of the water flowing through the water outlet channel 510 of the water outlet 500.

  For example, the temperature sensor can be provided in the water discharge nipple 520 of the water discharge unit 500. However, the position provided in the water outlet 500 of the temperature sensor is not particularly limited, and can be provided in any position of the water outlet 500.

  Further, the temperature of the water flowing through the outlet channel 510 measured by the temperature sensor is, for example, heated so as not to overheat the water when the water flowing through the heating channel R is heated by the heating unit 400 described above. It can be used to adjust the amount of heat generated in the portion 400.

  As shown in FIGS. 1 and 2, the embodiment of the instantaneous heating device 100 according to the present invention may further include a cover part 600.

  As shown in FIGS. 1 and 3, the cover part 600 can cover the water inlet part 200, the heating part 400, and the water outlet part 500. Such a cover part 600 stabilizes the connection between the water inlet part 200, the flow part 300, the heating part 400, and the water outlet part 500 even when the pressure of water entering the water inlet part 200 is relatively high. Can do.

  As shown in FIG. 1, the cover unit 600 may include a water inlet side cover member 610 and a water outlet side cover member 620.

  As shown in FIG. 3, the water inlet side cover member 610 can cover a part of the water inlet 200 and the heating part 400. Therefore, the water-inside cover member 610 can have a cylindrical shape with an open top. However, the shape of the water-inside cover member 610 is not particularly limited, and can be any shape as long as it covers a part of the water-inflow unit 200 and the heating unit 400.

  As shown in FIG. 3, the first exposure hole 611 may be formed on the lower surface of the water-inside cover member 610, for example, the water-inside cover member 610. Accordingly, the water inlet nipple 220 of the water inlet 200 can pass through the first exposure hole 611 and be exposed to the outside. And thereby, discharge members, such as a cock and a faucet, can be easily connected with the water entering nipple 220.

  A coupling groove 612 can be formed on the inside of the water inlet side cover member 610, for example, the opened upper portion of the water inlet side cover member 610. The coupling groove 612 may be L-shaped as shown in FIG.

  A coupling protrusion 622, which will be described later, formed on the water discharge side cover member 620 can be inserted into the coupling groove 612. Thereby, the water outlet side cover member 620 can be coupled to the water inlet side cover member 610.

  The shape of the coupling groove 612 is not particularly limited, and any known shape can be used as long as the coupling protrusion 622 of the water discharge side cover member 620 is inserted and the water discharge side cover member 620 can be coupled to the water inlet side cover member 610. It can be a shape.

  The water outlet side cover member 620 can be coupled to the water inlet side cover member 610. Furthermore, the water discharge side cover member 620 can cover the remaining part of the heating unit 400 and the water discharge unit 500.

  Therefore, the water discharge side cover member 620 can have a cylindrical shape with an open bottom. However, the shape of the water discharge side cover member 620 is not particularly limited as long as it can be coupled to the water intake side cover member 610 and cover the remaining part of the heating unit 400 and the water discharge unit 500. It can be a shape.

  As shown in FIG. 3, the second exposure hole 621 can be formed on the upper surface of the water discharge side cover member 620, for example, the water discharge side cover member 620. Accordingly, the water discharge nipple 520 of the water discharge unit 500 can pass through the second exposure hole 621 and be exposed to the outside. Thus, the water discharge nipple 520 can be easily connected to the water supply source.

  A coupling protrusion 622 may be formed on the outside of the water discharge side cover member 620, for example, the lower part of the water discharge side cover member 620 that is opened.

  Further, the lower part of the water discharge side cover member 620 can be inserted into the upper part of the water inlet side cover member 610. The coupling protrusion 622 of the water discharge side cover member 620 can be inserted into the above-described coupling groove 612 of the water intake side cover member 610 to couple the water discharge side cover member 620 to the water intake side cover member 610.
